There is no definite answer to this problem as it is written. However if one equal sign were changed to a positive sign, it is possible to solve the problem.

#### Explanation:

$9 - 3 w = 2 = 4 w$

The equation has two equal signs. More than likely, one of the two $=$ symbols was meant to be a $+$ symbol, since they are on the same key.

If we change one of the $=$ signs to a $+$ sign, technically it could mean $9 - 3 w + 2 = 4 w ,$ or $9 - 3 w = 2 + 4 w$.

One Possibility

$9 - 3 w + 2 = 4 w$

Add $3 w$ to both sides.

$9 + 2 = 7 w$

$11 = 7 w$

Divide both sides by $7$.

$\frac{11}{7} = w$

Switch sides

$w = \frac{11}{7}$

A Second Possibility

$9 - 3 w = 2 + 4 w$

Subtract $9$ from both sides.

$- 3 w = 2 + 4 w - 9$

$- 3 w = 4 w - 7$

Subtract $4 w$ from both sides.

$- 3 w - 4 w = - 7$

$- 7 w = - 7$

Divide both sides by $- 7$.

$w = 1$
